IMPROVEMENT IN CAR-SPRINGS.

Specificatio'n'forming part of Letters Patent No. 198,843, i June25,1877.'

Be it known thatI, GEORGE E. GonLEY of Philadelphia, and State of Pennsylvania, have invented following to be a full,

spiral spring so constructed that the coils thereof will be prevented from lateral disa bar having a ridge or head. on one side, a corresponding groove or depression on the so that when said spring under pressure the ribs or will enter the grooves on the other, and the bearing-shoulders come together, preventing lateral displacement of the coils. p 4 r Referring to the accompanying drawings, A designates a steel bar, having on one of its or tongue, a, having either a sides a rib, bead,

roundedor a sharp apex. or edge, a, and on f its opposite side a corresponding groove or depression, b. p i

dated January 1, 1878,- application filed eitherthe upper orlower side of the coils,and the groove the same.

In either case the rib or grooves of the adjacent coils in such'manner that said rib will enter said groove when the spring is compressed.

The rib or less width than the bar, so as to leave shoulders on each side, as shown at c c, to afford they come together.

not only are the coils prevented from lateral displacement upon one another under pressure, but the strength and resilient powers of the spring are increased by the formation of r the rib a. The bar can be formed so that when touch each other, either on the inner or outer bearing-shoulders the bar.

What I claim as my invention is- 1. A spiral spring having a bead or rib and and described.

2. A spiral car-spring made from a bar of metal whichhas'one or more ribs or beads, with corresponding groove or grooves on the opposite side, with one or more bearings or stantially as shown and described.
